I was pleased by the sound/performance of the headphones (for the price). Design is good because they stay on your head even when dancing. Instructions are a joke, but it doesn't really matter because you can figure it out. My only complaint is that the USB to Mini B5 charging cable developed a fault and I couldn't charge my Headphones properly at first, and after a few days I couldn't charge them at all. I bought a cheap replacement cable, and now they're fine.
